Consuming dairy products is vital to maintaining good overall health, and particularly important to bone health. However, there is limited research about how dairy products affect oral health. According to a new study, consuming cheese and other dairy products may help protect teeth against cavities.(1)

cheese This new study sampled 68 subjects ranging in age from 12 to 15, and the authors looked at the dental plaque pH in the subjects’ mouths before and after they consumed cheese, milk, or sugar-free yogurt. A pH level lower than 5.5 puts a person at risk for tooth erosion. If the pH level is above 5.5, there is less risk of developing cavities.(2)

cheddar The subjects were assigned into groups randomly. Researchers instructed the first group to eat cheddar cheese, the second group to drink milk, and the third group to eat sugar-free yogurt. Each group consumed their product for three minutes and then swished with water dental equipment. Researchers measured the pH level of each subject’s mouth at 10, 20, and 30 minutes after consumption.

sugar-free The groups who consumed milk and sugar-free yogurt experienced no changes in the pH levels in their mouths. Subjects who ate cheese, however, showed a rapid increase in pH levels at each time interval, suggesting that cheese has anti-cavity properties.

The study indicated that the rising pH levels from eating cheese may have occurred due to increased saliva production, which could be caused by the action of chewing. Additionally, various compounds found in cheese may adhere to tooth enamel and help further protect teeth from acid.

This in vivo study assessed plaque pH in subjects following the consumption of different dairy products. The results suggest that cheese has the highest anti-cariogenic property among the dairy products studied, and that milk and yogurt can be considered as non-cariogenic tooth scaler australia.

The relationship between nutrition and dental health has been a topic of interest for many years, and the cariostatic properties of cheese have been the subject of some research. Most of these studies suggest that the use of cheese as the final food in a meal will help to reduce caries. A 1991 study suggests several mechanisms by which cheese may reduce enamel demineralization have been proposed.(3)

Chewing cheese stimulates saliva flow. The alkaline nature of saliva buffers the acids formed in plaque portable dental unit. There is also an increased rate of sugar clearance due to the diluting action of cheese-stimulated saliva. Research has also suggested that chewing cheese may reduce the levels of cariogenic bacteria. This may be secondary to the reduced incidence of caries as conditions within a carious lesion tend to promote the growth of these organisms.

The high calcium and phosphorus content seems to be another factor in the cariostatic mechanism of cheese. Both casein and whey protein seem to be involved in the reduction of enamel demineralization. Casein phosphopeptides may also be responsible for some anticariogenicity by concentrating calcium and phosphate in plaque.

Eating cheese as part of a cooked meal (or on its own) may protect against dental caries. A small amount of cheese (15 g) is effective — this will not significantly contribute to fat intake. Recommending the consumption of cheese-containing meals is a positive approach to tooth decay prevention.
